Kida is the princess from Disney's movie "Atlantis: The Lost Empire" but since the movie was critically panned she's not often acknowledged by Disney Fans. Plus her movie was more of an action film anyway... sorta non-traditional princess.

Keroa: I'd say Kida is an "absolutely, definitely non-traditional princess", considering that she can take down a grown man in a fight and, at one point, even tries to stab an armed soldier with her own knife.
